Frauno, yes vCenter Server Heartbeat provides protection of SQL server databases stored on storage area networks. SAN mount to the server as locally attached and this is all we need to see, the good thing is the second server can be SAN, NAS or direct attached, they do not need to match up or be identical, just as long as the presented drive mappings are the same on both sides, the storage technologies can be different.
